Curse of the Shadow Borg : Season 1 Episode 26

When Vexor gets away with a piece of Drew's BeetleBorg armor, the BeetleBorgs head to Hillhurst hoping that Flabber can fix it. Using the piece of Blue armor, Vexor creates the Shadow Borg and sends it to Hillhurst to lure the BeetleBorgs into a trap. By using his weapon, the Shadow Claw, the Shadow Borg zaps the BeetleBorg powers from the kids, who realize they are no match against the Shadow Borg now.
